3 Claims.

The present invention relates in general to an improved mounting andfeed unit for an endless belt conveyer, and in particular the inventionis directed to a mounting and feed unit for an endless, boom-typetailings conveyer of a mining or ore treating machine or the like.

One of the objects of this invention is to provide, in combination withan endless, boom-type tailings conveyer which is adapted for bothhorizontal and vertical adjustment about corresponding axes adjacent itsinner end, a unique feeding assembly operative to feed material from themining machine onto said tailings conveyer from a fixed point above theinner end portion of the latter and regardless of its position ofadjustment, either horizontally or vertically.

A further object of this invention is to provide a structure as in thepreceding paragraph in which the feeding assembly includes a hopper,said hopper having a universal mount formed therewith which supports theinner end portion of the tailings conveyer in constant materialreceivingalinement or position under and relative to said hopper irrespective ofvertical or lateral swinging of the conveyer.

' An additional object of this invention is to provide a conveyermounting and feed unit which includes a hopper mounted in a fixedmaterial receiving position, a horizontal rotary collar mounted on thelower portion of the hopper in concentric and surrounding relation tothe hopmounting and feed unit forms a part, includes a swivel headblockmounted on said machine some distance above the hopper with the verticalaxes of said headblock and hopper being in alinement, and a block andtackle unit; the block at the outer end of the block and tackle unitbeing pivotally connected to the conveyer adjacent the outer end of thelatter, and the block at the inher end of the unit being pivotallyconnected to said swivel headblock.

A further object of the invention is to provide a simple and inexpensivedevice and yet one which will be exceedingly effective for the purposefor which it is designed.

These objects I accomplish by means of such structure and relativearrangement of parts as will full appear bya perusal of the followingspecification and claims.

In the drawings similar characters of reference indicate correspondingparts in the several views:

Figure 1 is a side elevation of the mounting and feeding unit asarranged in supporting relation between the inner end of an endless,boom type tailings conveyer and the frame of a mining machine.

Figure 2 is an enlarged fragmentary cross sectional elevation of theconveyer mounting and feed unit on line 2-2 of Fig. 1.

Figure 3 is an enlarged fragmentary longitudinal sectional elevation ofthe conveyer mounting and feed unit.

Figure 4 is an enlarged plan view of the hopper and rotary collarassembly, detached.

Referring now more particularly to the characters of reference on thedrawings, the numeral I indicates generally an endless, boom-typetailings conveyer, preferably driven by an electric motor (not shown)mounted in unitary relation thereon; the conveyer projecting outwardlyand normally at an upward slope from one end of a mining machine,indicated generally at 2. The mining machine includes a main or bedframe 3, and an upstanding frame structure 4.

The conveyer mounting and feed unit which is the subject of thisinvention comprises the following:

A hopper 5 is mounted in connection with and depends from a horizontaltop frame 6 which is secured by attachment brackets I to and projectsoutwardly from the frames 3 and 4 of the mining machine 2. Side tensionbars T extend from the outer end of frame 6 upwardly and inwardly toconnection with the upstanding frame structure 4 some distance above thehopper whereby to further support the latter. The hopper 5 is disposedsome distance above ground level and at its lower end includes acircular discharge opening 8, which is surrounded by a fixed horizontalring 9; said ring having an outwardly opening, annular channel I0 formedtherein, the bottom of which is formed by a removable ring 10a.

A collar plate ll surrounds the ring 9 and projects into the channel Inin supportedand turnable relation; said collar plate ll being elongatedon opposite ends, as shown, and includes suitable reinforcing elementsl2 along opposite sides.

a "vertical legs l3 are fixed in' connection with and depend fromopposite ends of said collar plate; and these legs straddle the innerend portion of the t'ailings conveyer l, the latter being fitted withoppositely projecting trunnions M- which are journaled in connectionwith the legs. The trunnions M are disposed ahead of the inner end ofconveyer I a distance somewhat greater than the diameter ofthe hopperdisa charge opening 8. Anupwardly and outwardly inclined deflector panI5 of generally U shape in plan is mounted on the conveyer I underthehopper 5; the legs or sides of said deflector pan overlying oppositeedges of the top run of the conveyerbelt 160i conveyer l in laterallyspaced relation to corresponding sides of the hopper opening 8,-whilethe end portion of said pan overlies and intersects belt 16 somedistance rearwardly of the opening 8. I

The upstanding frame structure 4 of the mini.- ing machine 2 includesamast or upwardly pro- Jecting A-frame l1 whi e is fitted with a swivelheadblock 18 overhanging hopper 5; the vertical axes of said headblockand the hopper being in vertical alinement and Suchl-ine intersectingthe horizontal agrial line oftrunnions 14, as clearly indicated in Fig,1.

The numeral IS'indicates a bl o cl; andtackle unit, the upper blocklflof saidunit being pivrjete ly on e d t the wiv l h adbloek l3 and thlower block 2| of the unitbeing pivotally connect'ed'by a yoke'2'2 tothe fco-nveyer l adjacent its outer end. The pulllead 23 leads to apower I winch (notshQW amounted on machine 2.

7. By reason of the abojreldes cribed"mounting an f e uni ,,-leosematerial .iedt to the h ppe 5 am ntinuous yd seha i e oint theu of belt[6 of cbnveyerl regardless of the .position of h ntal or verticaladjustment of said 1 v conveyer. V I

The conveyer when .moved for horizontal u ment, win s aheut he cente l e9 t hopper, and when vertically adjusted swings about the axis ofvtrunnionsM. The inner end portion oft-the upper runbf the conveyer I'remains at a t m s substantial y th a e p sition relative to hopperopening 8 and through Y which the materialvdischarges from said hopper.This assures that all niaterial-from the hopper fall onto the conveyerregardless of ,its position of a'djustment'. V V I,

' The tailings may bet-ed tram the min ng ma- 2,360,069 I a I V l chine'2 into the hopper 5 by any suitable mechanism. In the presentembodiment, however, the

tailings'are delivered from the mining machine" by a horizontallydisposed endless conveyer indicated generally at, 24. The discharge endof said conveyer is positioned beyondthe end of the main frame partiallywithin and intersecting 5 hopper 5, and is supported bybrackets 25; thehopper'being cut away symmetrical to said end portion of the conveyer 24so as to permit said -portion of the conveyer to be mounted asdescribed. t i 7 From the foregoing description it will be readily seenthat I have produced such a device as V substantially fulfills theobjects of the invention as set forth herein,
